PATENT OFFICE JOHN mas, or ELIZABETH, NEW JERSEY.

Patented 17,1912.

To all whom itmay coiwern:

Be it known that I, Join: PARA, a citizen of the United States of America, residing at. Elizabeth, in the county of Union and State of -New Jersey, have invented certain new and useful Improvements in Trolleys, of which the following is a specification, reference being had therein to the accompanying drawing. 1

This invention relates to trolleys'aml has for its object to provide. a device of such class with means in a manne as hereinafter set, forth for maintaining the trolley wheel in engagement with'the trolley wire and to further provide a device. with means in a manner, as hereinafter set forth whereby the that changes, variations and i'nodifications f can be resorted to which come within the scope of the claims hereunto appended.

In the drawin sP Fi ure 1 is a side elel'i D vation' showing a trolley in accordance with this invention in operative position with respect to a trolley wire, Fig. 2 is a vertical sectional view, broken away, Fig. 3 is across sectional view, one of the retaining wheels being shown in section, and Fig. .t is a rear elevation. I v Referring to the drawings in detail 1 de notes a trolley'pole provided at its upper end with a,. harp 2 having mounted in the arms thereof a shaft 3 secured in position by cotter pins 4. Eecentrically :mounted upon the sh'ait 3 within the harp 2 is a pair of vertically disposed plates 5 each provided near its torwa rd ed'gewrth. a vertically ex tending slot (3. Each of said plates 5 has projecting from its upper forward corner an inclined arm 7 and furtherhas projecting from its rear uppercornera' circular extension 8 Moimted in the arms' 7 is a shaft 9 carryin-g a roller 10 which is adapted, when thetrolley is in operative position, to travel against the trolley wire 11 and mounted in] the extension 8 is a shaft12 having revolu bly mounted thereon a trolley wheel 19 which engages the trolley wire 11 whenthe trolley is in operative position.

Interposed betweenthe plates 5 at their real-lower corners is acrossmember lat provided'with a slot 15. Arranged between the plates 5 and having its forward end' pivot'-' ally mounted upoirthe cross bar 16 is a resiliently supported holding member 17. 'lhe latter at its "rear end is offset with respect to its torward portion and has lixed'theret-o a depending curved arm 18 which extends through the opening 1?. Surroumlmg the arm 18 and interposed between the members 14, 17 is a coiled spring 19, the i'un'ction of which is to maintain the rear end of the member 17 elevated. Connected to the memher- 17 is a lowering cable 20 which when pulled dowmvardly will shift the rearof the member 17 upon its pivot 16 against. the elevating action thespring t l lxt'ending between the plates as well as being secured thereto at the t p'ot the forward portion of said plates. is :1 pair of spaced supports 21 ha ving arrhngcd there between a pair of curved and oppositely dis fposed shitting arms 22, 23- having their lower ends resting upon a vertically movable .ictuating block 24 which is positioned between the plates 5 and rests upon the mem ber 17. The plate 24 is provided with a pair ot' oppositely disposed lugsifi whichextend into the opening (3. The lower ends of the arms 22, 2?) alsoextend through the opening 6 but permanently rest upon the top edge of the bloclcQ t. The arms 22, 23 are pivotally mounted upon a pin 27 which extends through the said arms and supports 21.

Projecting from each of the arms 2'). is an inclined shaft 28 carryinga holding rollerQt). The shafts 28 are oppositely disposed with respect to each 'other and the rollers 29 are mounted.upon. said shafts at an inclination. 'l-hc rollers are above the plates 5, projecting'toward each other and have their edges thereofgrooved at 30 so that when the rollers are in abut-.

arranged I the trolley wire 11, due tothefact that the rollers overlap the wire 11. Therollers 29 are of such ,weight that they will over-- balance the lower ends of the arms 22, 23-

when these latter are not supported 'by the block 24. It will be assumed that the parts are in the position as shown in Fig. 3. By pulling downwardly on the member 17 ,the

lock 24 is lowered releasing the' arms 22 and 23 whereby the weight'of-the rollers 29 will cause the arms 22 and 23 to rock on their pivots 27, the rollers 29 swinging away from each other, which enables the trolley to be disconnected from the trolley wire 11'.

The roller 01' wheel 10 is utilized as a guide and to also prevent, in connection with the trolley wheel 13, the trolley shifting above the wire 11' when the rollers 29 are moved apart.

What I claim is:

1. A trolley comprising a pole, a harp carried thereby, a pair of vertically disosed plates eccentrically mounted in said arp spaced from each other, a trolle wheel journaled in said plates, a pair of olding I rollers carried by said plates and adapted to overlap the trolley wire for maintaining the trolle wheel in engagement with said wire, shi ing arms for said rollers, a vertically movable plate engaging with said arms to prevent the shifting movement thereof a spring controlled support for said vertically movable plate, and means for lap the trolley wire for maintaining the trolley wheel in engagement with said wire,

shifting arms for said rollers, a vertically movable plate engaging with said arms to prevent the shifting movement thereof, a spring controlled support for said vertically movable plate, means for shifting said support to permit of the lowering of said vertically movable plate and the shifting of said arms so said rollers can move a art, and a guide roller connected to said-p ates rearwardly' of said holding rollers. i

In testimony whereof I aflix my signature in the presence-of two witnesses.
